Improved sap-spile

FATENT Ormeso J. M. LE COUNT, OF HARTFORD, VISCOSIN, AND G. R. BOYNTON, OF

CHICAGO, ILLINOIS.

IMPROVED SAP-SPILE.

Specification forming part of Letters Patent No. 39, R55. dated July 7, 1863.

To all whom t may concern:

Be it known that we, J. M. LE COUNT, of Hartford, county of Vashington, State of NViseonsin, and G. R. BoYNToN, of the city of Chicago, county of Cook, State of Illinois, have invented a new and useful Machine for Forming Sap-Spiles from Sheet Metal, and we do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view; Fig. 2, a

l cross-section through the line C D; and Fig.

3, a plan of the narrow end of said machine, showing the movement of the hinged journalbox. j-

To enable others skilled in the art to make and use our invent-ion, we will proceed to deseribe its construction and operation.

A, Fig. l, is a block of metal constructed in any suitable manner, so that it may be secured to a bench for convenience and facility of operation. Said block A has a cylindrical tapering groove or seat through its entire length suitable to receive within said groove the taper spindle or shaft S. At the broad end of A there is a journal-box to support the large end of the shaft S, and at the opposite end of A is a hinged bearing for the conical journal on the small end of said shaft. The shaft S is operated by a crank attached to the large end outside of the journal-box, and has running boxes one or more splines or channels of sufcient size to receive the edge of the piece of metal to form the spile. Then a spile is to be formed, a piece ofrnetal of suitable dimensions for said spile is inserted into one ofthe aforesaid channels. Then a revolution of t-he shalt S is made, which gives the piece of nietala concave forni and turns a iiange on one edge. Then said piece is taken out of the channel and the other edge inserted into the same, when a reversed motion is given to the shaft sufficient to turna flange on the opposite edge, and the spile is complete.

R is a roll with a bearing at either end. Its use is to prevent the piece of metal as it is l drawn under the shaft S from making a short open. There is a conical journal on S at t', s

Fig. 3, which tits into a corresponding bearing in J. When J is in its proper position, as seen at Fig. l, it is secured by a bail, r, thrown over the end, to hold it from swinging or rising when the machine is in use. The object ot' said hinged journal is that a complete cylinder may be formed by inserting one edge of a piece of metal into one of the channels in S. Then by giving S a revolution the piece of metal is turned completely around it. The bail r is then .thrown back and J swung outward, when the cylinder may be readily slipped off the small end of the shaft S.

Fig. 2 is a section of A through the line C D, Fig. l.

o, Fig. 2, is a slot or opening through the bottom of A to allow the escape of scales and dirt which may gather under the shaft S.

The cylindrical groove in A is deeper at the.

right hand or crank end than at the opposite end, which gives an inclination to the bottom .of said groove toward the crank end, so that scales and dirt work toward the opening and fall through at 0.

Fig. 3- is a plan view showing the location of the shaft S, roll R, and the swing of the I journal-box J. through its entire length between the journal- These several parts need no further description, having been fully described on Fig. l.

That we claim as our invention isl. A machine for forming sap-spiles from' J. M. LE COUNT. G. R. BOYNTON.
